Examples disclosed herein relate to receiving a record of a data transaction between two participants, creating a ledger entry associated with the record of the data transaction, appending the ledger entry to a subset of a plurality of partial ledgers associated with a blockchain, and updating a table of contents associated with each of the plurality of partial ledgers associated with the blockchain.

Blockchain partial ledgers

Examples disclosed herein relate to a traceability identifier method comprising assigning a traceability identifier to a data element, wherein the traceability identifier comprises a plurality of identifier segments, receiving a request for the data element to be included in an analytics report, determining, according to the traceability identifier, whether the data element is permitted to be included in the analytics report, and in response to determining that the data element is permitted to be included in the analytics report, providing the data element for use in the analytics report.

Traceability identifier

An example print system is described as including a manager engine that identifies an attribute of a job, a discovery engine that identifies a service printer available to store the job, a transfer engine that causes the job to transfer from a first printer to a second printer, and a remote job engine that maintains job retrieval information associated with the job.

Transfer jobs to service printers

An embedded marker system includes a plurality of devices communicatively coupled to a single system model. The system further includes a plurality of application views configured to communicate with the system model to obtain status and configuration data associated with one of the plurality of devices.

Capability to build multiple application views from a single system model

A device and method for assisting a user to clear a media jam in a printing device that announces pages, picks media responsively to the announced pages and images the picked media using a media transport path, that: detects a media jam at a given location along the media transport path; halts printing device components upstream from the given location in the media path while continuing to image picked media downstream from the given location in the media transport path; and, prompts the user to clear the detected media jam from the given location after all downstream media has been imaged.

Printing device and method

A printing device can receive a replaceable component that includes an integrated memory. The integrated memory can store an indicator for indicating a condition of the component. The printing device can retrieve the indicator from the integrated memory. The printing device can determine from the indicator the condition of the component. The printing device can monitor for an occurrence of a trigger event. The printing device can, if the component is determined to be in a first condition and a trigger event occurs, increment a component usage count. The component usage count can be stored in a memory internal to the printing device.

Tracking component usage in a printing device

A system and method are provided for correcting a hang condition caused by an unanticipated exception during a printing process. The method may include providing a set of predetermined rules according to which the print process modules interact to control the printing process. The method further may include monitoring, from a self-correcting module, a state of each of a plurality of the print process modules. The method may also include determining that the printing device is hung during a printing process, based on at least one predetermined rule and the state of at least one print process module, and setting the state of at least one print process module to a default condition.

Self-correcting printing system

A printing system is described. The printing system includes a printer capable of utilizing print material contained by a cartridge. The printer is capable of detecting when the level of the print material is at a different one of a plurality of pre-determined levels. The printer is also capable of counting pixels. The printer can periodically estimate the remaining life of the cartridge using a reference print material level and the change in pixel count since the print material was at the reference material level.
